MIXING Nozznn.

Application tiled October `18, 1926. Serial No. 142,467.

This invention relates particularly to nozzles in which concrete isvmixed and through which the concrete is forced under pressure onto astructure. Heretofore, in nozzles of the above mentioned character itwas extremely difficult to properly mix the water with the dry aggregateto obtain a concrete or cement of proper strength.

An object of my invention is to provide a mixing nozzle in which thewater is thoroufhly mixed with the dry aggregate.

Another object is to provide a nozzle 1n which the amount of water inthe various parts of the nozzle may be regulated to suit the particularconditions.

A further object is to provide a nozzle 1n which the shape of the streamemitted therefrom can be varied.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description, the appendedclaims, or in the operation of the device.

In the drawing- Fig. 1 is a side elevation of my nozzle.

Fig. 2 is a sectional view taken on line 2, 2, Fig. l.

Fig. 3 is an end view.

Fig. 4 is a sectional view taken on line 4, 4, Fig. 2.

Referring more particularly to the draw- The numeral 1 indicates ahollow annular water ring of my nozzle into which a water the flow ofwaterthrough said pipe being controlled by the valve 3. A fitting 4screws into the ring 1 and a iiexible hose 5 is suitably securedthereto, said hose conveying the dry aggregate to the nozzle. Vanes 6are secured in the fitting 4, said vanes extending rearwardly into thehose 5 and forwardly into the nozzle. These vanes may consist of crossedmetal plates as shown in Fig. 4, or they may be curved or otherwiseformed to suit the particular conditions required. It will be seen thatthe vanes 6 divide the hose 5 and fitting 4 into a plurality ofcompartments 7 ,v through which the dry aggregate passes, thatis, thestream of aggregate is divided into a plurality of smaller streams whichare more readily saturated and mixed with the water as will behereinafter described A plurality of nozzles 8 extend inwardly throughthe water ring 1, there being one or more nozzles for each of thecompartments 7 formed by the vane 6. The water fed into the ring 1 bythe pipe 2, passes through the nozzles 8 into the stream of dryaggregate passing through the nozzle, thoroughly saturating theaggregateand forming a properly mixed concrete. l l

Each of the nozzles 8 are provided with an adjusting screw 9 by means ofwhich the ilow therethrough is controlled. A plug 10 is provided in thering 1 which may be removed to adjustthe nozzles, or if desired theadjusting screw may extend through the ring so that the adjustment maybe made from the outside.

To carry the water to the center of the stream passing along the vanes6, I provide4 one or more of said vanes with conduits 11, said conduitsopening into an annular groove 12 in the fitting 4, and a plurality ofducts 13 extend from the water ring l into said groove. Thus it will beseen that a supply of water is maintained lat the center of the streamof aggregate passing through the nozzle.

A conical hood 14 screws onto the water ring 1 and the end thereof isprovided with a baiiie 15 through which a plurality of outlet ports 16extend. The purpose of the ba-iiie 15 is to cause an eddy or mixingmotion within the nozzle which more thoroughly combines the variouselements of the concrete. By varying the size and position of the outletports 15,1 provide any shape l desired for the outgoing stream otconcrete. If a different shape is desired the hood 14 can readily beremoved from thel water ring, and a new hood inserted having the numberand position of outlet ports required to give the desired effect.

Having described my invention, I claim:

1. A mixing nozzle comprising a water ring, means to vconduct water tosaid ring, a' dry aggregate hose4 extending to said nozzle, and vanes insaid dry aggregate hose, and nozzles extending from said water ring,said nozzles extending inwardly in the spaces formed by said vanes.

2. A mixing nozzle comprising a water ring, means to conduct water tosaid ring, a dry aggregate hose extending to said nozzle, and vanes insaid dry aggregate hose, and nozzles extending from said water ring,said nozzles extending inwardly in the spaces formed by said vanes, andmeans to adjust said nozzles to. regulate the liow therethrough. l

3. A mixing nozzle comprising a Water rinlggf means to conduct water tosaid ring, a tting extending. into said ring, intersecting vanes in saidfitting, said vanes forming passages through which the dry aggregatepasses, and nozzles extending inwardly from said Water ring, into thespaces between said vanes.

4. A. mixing nozzle comprising a Water ring, means to conduct water tosaid ring, a fitting extending into said ring, inter- Secting vanes insaid fitting, said vanes forming passages through which the dryaggregate passes, said vanes having Water chan# nels formed therein,said channels opening f into said water ring, whereby water is conductedto the center of the flow through said fitting.

5. A mixing nozzle comprising a water ring, means to .conduct water tosaid ring, a iittingl extending into said ring, intersecting vanes insaid fitting, said `vanes forming passages through which the dryaggregate passes, said vanes having water channels formed therein, saidchannels opening into said watel1 ring, whereby water is conducted tothe center of the How through said fitting, and nozzles extendinginwardly from .said water ring and means to adjust the flow through saidnozzles.

6. A mixing nozzle comprising a Water ring, means to conduct water tosaid ring,

and dry aggregate hose extending centrally 85 mixing nozzle comprising awater 40 ring, means to conduct water to said ring, and dry aggregatehose extending centrally through said ring, a conical hood threaded ontosaid ring, a baille in the end of said hood, said baille having aplurality of holes extending therethrough, intersecting vanes in saiddry aggregate hose, and nozzles ex-` tending inwardly from said waterring.

8. A mixing nozzle comprising a. water ring, means to conduct water tosaid ring,

a fitting extending into said ring, intersecting vanes in said fitting,said vanes forming passages through which the dry aggregate passes, andnozzles extending inwardly from said water ring, into the spaces betweensaid vanes, and a conical hood secured to said ring and extendingforwardly from the ring.

In testimony whereof I aix my signature.
